The displays use metallic films featuring various shape memory alloys which are produced layer by layer on silicon wafers using thin film technology. Display pixels are generated when the metallic film adjusts its curvature partially, similarly to bimetal snap plates for temperature switches. The movement of the films is then transferred to the touch panel via plastic pins und thus can be detected by the user.
